I don't read Right for Scotland on a regular basis, but this post makes for seriously interesting reading.
In essence the debate about 28 days or 42 days of detention is rubbish. From computers the whole thing can actually be done in 2 or 3 days, and then an interrogation of suspects where the police actually have all the answers and they either admit it, and get a reduced sentence, or don't, and get a longer one.
As RFS says, viewers of The Bill will know it as CrimInt.
So when Mr. Brown talks crap in the HoC, get your MP to stand up and tell him so.
